Math.TFPURoundingMode Enumeration

TFPURoundingMode defines how the FPU handles rounding issues.

Pascal

TFPURoundingMode = (
  rmNearest,
  rmDown,
  rmUp,
  rmTruncate
);

C++

enum TFPURoundingMode {
  rmNearest,
  rmDown,
  rmUp,
  rmTruncate
};

Description

The FPU (Floating Point Unit) handles floating point calculations. GetRoundMode is used to read, and SetRoundMode is used to set the rounding mode, with TFPURoundingMode defining this mode.

TFPURoundingMode can be one of the following values :

Value	Meaning
rmNearest	Rounds to the closest value.
rmDown	Rounds toward negative infinity.
rmUp	Rounds toward positive infinity.
rmTruncate	Truncates the value, rounding positive numbers down and negative numbers up.
